Through proper arrangement of guide pulleys in the horizontal and vertical direction, the movement of the four wire ropes can effectively prevent the swing of the spreader, greatly improving container hoisting efficiency.

The new-developed four rope anti-sway system (Patent number: ZL201220568248.4) effectively achieve bidirectional anti-sway of the spreader. This system allows a ±250mm movement of spreader in the gantry or trolley direction, greatly improving container hoisting efficiency.

Based on the data stored from the mechanism positions and the containers on the yard as well as database management automatic tracking operation and the most optimized tracking control of the mechanisms can be realized, increasing the working efficiency and ensuring safety

Software intelligent deceleration technology and hardware inspection protection device are applied to adjust the time and position of deceleration dynamically. This helps decrease crush and wheel load, thus increasing service life and stability of the crane.

Equipped with two independent sets of anchoring device resisting horizontal force, four sets of ropes resisting overturning torque, four sets of anti-creeper or wheel clamp resisting gust, the system ensures the stability of the whole machine. Optional electric iron wedge, wheel clamp, rail clamp, rail jack and other wind proof devices are convenient and reliable.

Deflection of bogie relative to the rail is detected in real-time as the control signal for the transducer to control motor speed. The bogie deflection can be corrected manually (or

automatically)to prevent rail gnawing, thus ensuring safe operation, reducing wearing between wheel and rail, and span service life of crane

Active inverter technology is applied to transfer the stored dynamic power and potential power into electricity and be recycled to the grid. At the same time, it can resist the pollution to grid from higher harmonic voltage, thus increasing the power factor of the equipment.

Full automatic resonance eliminating reactive power compensation device is configured to achieve the average power factor above 0.9 or more, which improves electricity efficiency and reduces wire consumption.

Complete processing equipment for steel pretreatment , cutting, bevel cutting, bending forming and other material processing are applied to provide a powerful guarantee on welding quality.

As the launching of the first semi-automatic welding assembly line for heavy port machinery, the box beam welding cycle has been shortened by 15%. By applying semi-automatic car welding of H-beam, the welding cycle of stay bar system and M-house base has been shortened by over 30%. Large structures including boom and girder can be welded complete in the factory, and the UT qualification rate is over 99%.

As the launching of new industrial park, super-large parts blasting, component painting, and assembling can be processed in the factory. We ave ended the past era of outdoor processing to guarantee the production cycle and product quality
